Abstract:

Ti-containing zeolites showed extremely high activity and selectivity in numerous friendly environmental oxidation reactions with hydrogen peroxide as a green oxidant. It will be in high demand to synthesize Ti-containing crystalline extra-large-pore zeolites due to the severe restrictions of medium-pore and/or large-pore zeolites for bulky reactant oxidations. However, the direct synthesis of extra-large-pore Ti-zeolites was still challengeable. Here, we firstly report a strategy to directly synthesize high-performance Ti-containing CFI-type extra-large-pore (Ti-CFI) zeolites assisted with fl

Abstract:

The isomorphic substitution of two different metals (Mg and Co) within the framework of the ITQ-51 zeotype (IFO structure) using bulky aromatic proton sponges as organic structure-directing agents (OSDAs) has allowed the synthesis of different stable metal-containing extra-large-pore zeotypes with high pore accessibility and acidity. These metal-containing extra-large-pore zeolites, named MgITQ-51 and CoITQ-51, have been characterized by different techniques, such as powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectrometry, UV–Vis spectroscopy, temperature p

Abstract:

Lewis acid zeolites containing tetravalent metals, such as Sn or Zr, are of great interest as catalysts for various reactions owing to their tunability, activity, and reusability. In the context of emerging trends in biomass-related substrates processing, the synthesis of Lewis acid zeolites with extra-large pores presents a key step by addressing diffusion restriction associated with these molecules. In this paper, we report on the incorporation of Sn and Zr into extra-large pore zeolites UTL and *CTH through a four-step approach, including synthesis of parent germanosilicate zeolites, follow

This chapter examines the internal competition and coordination in mobilising resources from regular and extra-budgetary sources at the six IOs. As the traditional assessed contribution from member states to IOs has been by and large fixed and the share of other sources has been expanding, the challenge for IOs is how to manage (a) the contribution from different parts of member states (assessed vs. voluntary contribution), (b) that of member states and non-state contributors, and (c) the participation of non-state bodies in IO activities which pose serious challenges for the head of IOs, the

AbstractThe compaction effect of extra-long prestressed high-strength concrete (PHC) piles in deep soft soil foundation was studied by field test. The pore water pressure gauge, inclinometer were embedded in different plane positions or different depths of the foundation to monitor the pore pressure and deformation of the foundation when driving pile. The research shows that the magnitude of excess pore water pressure caused by single pile installation is mainly related to buried depth of the measuring point and the linear distance between the pile tip and the measuring point.

Abstract:

During driving of displacement piles, soils within a few pile diameters can undergo large shear deformation. Furthermore driving of displacement piles strongly compresses adjoining soils and leads to build up of excess pore water pressure. This temporary build up of excess pore water pressure, coupled with the sensitivity of the clay, causes the soil to lose a good fraction of its shear strength in the short term. Dissipation of the excess pore pressure generated during pile driving may allow pore pressure to rise in the vicinity of a slope, thus leading to failure of the slope, even where the

Characterizing these systems requires a peculiar type of modeling that is based both on measurements and assumptions since the geometry of the pore network extends beyond the well, residing in an intermediate scale that cannot be fully me

The production of directional wells in the early stage of development was much lower than that of the ODP design.

One of these problems is the big waiting time at the ports that reaches 12% of the global fleet around the world at any given moment.
